Let’s face it, athletic wear isn’t known for having great pockets. Not to mention, who wants the bulk when you’re running or in the gym? Here are a few clever water bottles with hidden compartments to hold a key, cash and your ID. Check out the metal Sport and Store Woof Woof Water Bottle (on the left, $19.95) or the BPA-free Contigo AUTOSEAL Kangaroo Water Bottle ($13.22). What a great way to bring along your EBOOST and valuables on your workout!
